The Federal Government is moving to repeal new agricultural and veterinary chemical regulations that would require companies to periodically re-register their products to prove that they remain safe to use.

Labor's agvet chemical registration changes were revealed to be among a raft of regulations the Federal Government will move to repeal next week.

The former government's changes to agricultural and veterinary chemical laws were passed last year, and are due to come into effect from July 1 this year.

Former agriculture minister, Senator Joe Ludwig, and other supporters of the change argue that mandatory re-registration shifts the onus onto chemical companies, to prove that the products they sell remain safe for humans, animals and the environment.

But the changes were strongly opposed by the Coalition, farm groups and chemical companies, which argued the laws would cost the agriculture sector an additional $2-8 million per year.

The repeal will pass the House of Representatives, but may face trouble in the Senate. Both Labor and the Greens previously voted in favour of mandatory chemical re-registration.
